How to become a full stack developer? As one of the hottest topics for developers, the discussions have never stopped. On LinkedIn and Facebook, lots of people put their job title as a full stack developer. Besides, it seems that the “Full Stack” topic has already become a new job trend. An article on Medium has discussed the full stack designer getting both praise and blame. Some people think that the full stack is just a title, what he/she should focus on is the real personal ability and technology.

Essentially, I think the discussion about the full stack is also a kind of argument relating to the all-rounder and expert in the IT industry, and debate on the depth and breadth of development skills.
